I, Bruce Bragagnolo, certify that:

| | 1. | I have reviewed this annual report on Form 40-F of
      Timmins Gold Corp.;                                                                                                                                                                                                                                                                        
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |    |                                                                                                                                                                                                                                                                                                                                                     
| | 2. | Based on my knowledge, this report does not contain any
      untrue statement of a material fact or omit to state a material fact
      necessary to make the statements made, in light of the circumstances under
      which such statements were made, not misleading with respect to the period
      covered by this report;                  
| |    |                                                                                                                                                                                                                                                                                                                                                     
| | 3. | Based on my knowledge, the financial statements, and
      other financial information included in this report, fairly present in all
      material respects the financial condition, results of operations and cash
      flows of the issuer as of, and for, the periods presented in this
      report;                                         
| |    |                                                                                                                                                                                                                                                                                                                                                     
| | 4. | The issuers other certifying officer and I are
      responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and
      internal control over financial reporting (as defined in Exchange Act
      Rules 13a-15(f) and 15d-15(f)) for the issuer and
have:

(a) designed such disclosure controls
and procedures, or caused such disclosure controls and procedures to be designed
under our supervision, to ensure that material information relating to the
issuer, including its consolidated subsidiaries, is made known to us by others
within those entities, particularly during the period in which this report is
being prepared;

(b) designed such internal control
over financial reporting, or caused such internal control over financial
reporting to be designed under our supervision, to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted
accounting principles;

(c) evaluated the effectiveness of the
issuers disclosure controls and procedures and presented in this report our
conclusions about the effectiveness of the disclosure controls and procedures,
as of the end of the period covered by this report based on such evaluation; and

(d) disclosed in this report any
change in the issuers internal control over financial reporting that occurred
during the period covered by the annual report that has materially affected, or
is reasonably likely to materially affect, the issuers internal control over
financial reporting; and

| | 5. | The issuers other certifying officer and I have
      disclosed, based on our most recent evaluation of internal control over
      financial reporting, to the issuers auditors and the audit committee of
      the issuers board of directors (or persons performing the equivalent
      functions):
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(a) all significant deficiencies and
material weaknesses in the design or operation of internal control over
financial reporting which are reasonably likely to adversely affect the issuers
ability to record, process, summarize and report financial information; and

(b) any fraud, whether or not
material, that involves management or other employees who have a significant
role in the issuers internal control over financial reporting.
